Klinikinis medicinos priemonių įvertinimas (ISO/DIS 18969:2025)

This document specifies terminology, principles and a process for the clinical evaluation of medical devices. The process described in this document aims to assist manufacturers of medical devices to estimate the clinical risks associated with a medical device and evaluate the acceptability of those risks in the light of the clinical benefits achieved when the device is used as intended. The requirements of this document are applicable throughout the life cycle of a medical device. The process described in this document applies to the assessment of risks and benefits from clinical data obtained from the use of medical devices in humans. This document specifies general requirements intended to — verify the safety of medical devices when used in accordance with their instructions for use; — verify that the clinical performance or effectiveness of a medical device meet the claims of the manufacturer in relation to its intended use; — verify that there is sufficient clinical evidence to demonstrate the achievement of a positive benefit/risk balance when a medical device is used in the intended patient population in accordance with its intended use; — ensure the scientific conduct of a clinical evaluation and the credibility of conclusions drawn on the safety and performance of a medical device; — define the responsibilities of the manufacturer and those conducting or contributing to a clinical evaluation; and — assist manufacturers, clinicians, regulatory authorities and other bodies involved in the conformity assessment of medical devices. Note 1 This standard can be used for regulatory purposes. Note 2 This document does not apply to in vitro diagnostic medical devices. However, there may be situations, dependent on the device and national or regional requirements, where sections and/or requirements of this document might be applicable.

Techninė keramika (modernioji keramika, modernioji techninė keramika). Bandymo metodai monolitinės keramikos atsparumui trūkimui nustatyti. Bandinio su vienpuse V įpjova metodas

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm. The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.

Naftos ir dujų pramonė, įskaitant mažesnio anglies dioksido pėdsako energijos gamybą. Medžiagos, naudojamos vandenilio sulfido (H2S) turinčiose aplinkose išgaunant naftą ir dujas. 1 dalis. Medžiagoms ir jų apdorojimui keliami reikalavimai (ISO/DIS 15156-1:2025)

This document describes general principles and gives requirements and recommendations for the selection and qualification of metallic materials for service in equipment used in oil and gas production and in natural-gas sweetening plants in H2S-containing environments, where the failure of such equipment can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements given in the appropriate design codes, standards, or regulations. This document addresses all mechanisms of cracking that can be caused by H2S, including sulfide stress cracking, stress corrosion cracking, hydrogen-induced cracking and stepwise cracking, stress-oriented hydrogen-induced cracking, soft zone cracking, and galvanically induced hydrogen stress cracking. Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions. This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see Clause 5. This document is not necessarily applicable to equipment used in refining or downstream processes and equipment.
